摘要
线性宽域氧传感器能够连续检测空燃比为10～20的混合气,相当于过量空气系数0.686～1.405,测量范围广,尤其能进行过稀混合气的测量。通过分析,该传感器信号电压为0～5V,其工作曲线平滑、线性度极强,并且检测方法简单。随着内燃机稀燃技术的推进,其应用无疑越来越广。
Linear wide domain oxygen sensor can continuously detect air-fuel mixed gas ratio is 10 to 20,equivalent to the excess air coefficient 0.686 to 140.5,measuring range wide,especially for thin mixed gas measurement.through the analysis of the sensor signal voltage 0 ～ 5V,and the working curve smoothing,linearity is strong,and the detection method is simple,as the engine lean combustion technology advance,the application will undoubtedly become more and more widely.
